DUlVlPING-WAGON.

SPECIFICATION forming part of Letters Patent No. 445,981, dated February10, 1891.

Application led April 7, 1890. Serial No. 346,976. (No model.) i

To all whom, t may concern:

Be it known that I, JAMES T. DOUGINE, a citizen of the United States,:residing in Chicago, in the county of Oook and State of Illinois, haveinvented a new and nseful invention in Dump-iVagons, of which thefollowing is a specification.

My invention relates to dump-wagons.

The object of my invent-ion is to provide a dump-wagon havingahingesectional bottom, the contiguous sections of which open or swingin opposite directions, so that the break or opening in the bottom ofthe box formed by dropping the sections may be double the width of onesection.

A further object is to provide a dumpwagon of a strong, simple, andefficient coustruction, the alternate sections of which are dumped oroperated simultaneously, so that when such alternate sections aredropped or opened if the load does not begin to break or discharge atone part it may at another, and whereby all the sections may be openedor dumped without lifting or raising any of the sections or any portionof the load thereon. This very greatly facilitates the dumping ordischarge of the load, and especially when it is composed ot' stone,sticky clay, or other materials, which 'by the jolting action of thewagon in hauling` the load over any distance of rough road will tend toarch itself against the sides of the box or compact together into asolid mass. Vith many wagons heretofore in use the difficulty of dumpingo1' discharging loads of many kinds of material is such that the utilityof the dump-wagon is largely lost.

A furbther object of my invention is to provide a dump-wagon the hingesections of which may not only be dumped, but may be restored toposition by the driver without leaving his seat.

A further object is to so construct the wagon that a portion of the loadmay be dumped and the dropped or dumped sections restored to theirposition or closed without dumping the remainder of the load. A

My invention consists in the means l employ to accomplish these obj ectsor resultsthat is to say, my invention consists in a dump-wagon havingabottom composed'of tion, such hinge bolts or shafts being alsolfurnished with operating-arms pivoted to a common operating-bar.

It further consists in providing the oscillating bars which support thefree meeting ends of the sections with operating-arms pivoted to acommon connecting-bar, so that these oscillating supporting-bars may besimultaneously' moved to dump each alternate section.

It further consists in the novel devices and novel combinations of partsand devices herein shown and described, and more particularly pointedout in the claims.

In the accompanying drawings, which form a part of this specification,and in which similar letters of reference indicate like parts, Figure lis a plan View of a device embodying my invention. Fig. 2 is a sideelevation. Fig. 3 is a section on line 3 3 of Fig. 1. Fig. 4 is anenlarged detail section taken` on line #l 4 ot Fig. 1, showing theconstruction 0E the arm, cam, or projection on the rocking shaft whichserves to raise the section. Fig. 5 is a side view of the device shownin Fig. 4. Fig. 6 is an enlarged detail side elevation of theoscillating support or b ar upon which the meeting ends of the sectionsrest, and by the oscillating movement of which they are dumped. Fig. 7is a cross-section on line 7 7 of Fig. 6. Fig. S is an enlarged detailsection on line 8 8 of Fig. 1, showing the form of the hinge. Fig. 9 isa detail cross-section taken on line 9 9 of Fig. 1, showing the supportsfor the box which elevate it above the axle or bolster.

In the drawings, A A represent the wheels 5 A A', the front and rearaxles; A2, the front bolster; B B, the sides of the box; C O, thestandards or supports upon which the sides IOO of the box rest and whichserve to elevate it above the rear axle and the front bolster, and thusgive room for the front wheels to turn under the box, and for theoperation of the devices, hereinafter to be described, for raising thehinge-sections D D of the box-bottom, as well as to give room foi` theproper swinging of each pair of hinge-sections, the shaft or hinge-boltof which is located abov the rear axle or front bolster.

F is a rocking hinge bar or shaft through which each pair of sections DD is hinged together by the eyes or sleeves d, formed upon the edges ofthe sections. The construction of the hinges d at the edges of thesections is much the same as that of an ordinary strap-hinge, exceptingthat the sleeve d is, or should preferably be, made about twothirds of acircle, as indicated at Fig. 8, to give room for the escape of sand ordirt from the hinge. Each hinge-shaft F is furnished with a projectingarm or cam f f, adapted to engage against the section D or D and elevateor restore the saine to position. The cams or projections f I prefer tomake of the loop construction shown in Figs. 4 and 5, as that is asimple construction and affords a very rigid means of securing the sameto the shaft F by a bolt and nut f f2, which serve to clamp the loopabout the shaft. The hinge-` shafts F are journaledA in suitablebearings F', rigidly secured to the box-sides B. The hinge-shafts F areprovided with operatingarms F2, which are pivoted to a commonconnecting-.rod G, which is connected to an operating-arm G. rlhe bottomof the box may be provided with any desired number of hinge-sections DD. l however prefer to employ five for use in a box of ordinary length.rlhe free or meeting ends of the hinge-sections D D rest uponoscillating supports H, which are journaled in suitable bearings Hattached to the sides of the box l5. These oscillating supports H have acurved web or face h for the edges of the leaves or sections D D to restupon, so that the supports H may be rocked or oscillated without liftingor raising the sections resting thereon or any portion of the load. Theoscillating leaf-supporting bars H are furnished with operating-arms h,which are pivoted to a common operating or connecting bar K, connectedwith the dumping-lever K. The dumping-lever K may preferably be madeintegral with or connected rigidly to the operating-arm of the frontoscillating bar, as this brings thedump-lever in convenient positionforoperation, and saves the necessity of providing a separate pivot orbearing for the dump-lever, and also somewhatsimplitles theconstruction.

Then it is desired to dump only one or more sections at a time, theoperating-arms of the other leaf-supporting or dumping bars H may bedisconnected from the operating-bar K by simply removing the connectingor pivot pins, so that the movement of the dump-lever K will only dumpthe sections desired.

The du 1n p-lever K is provided with a guard K2, secured tothe side ofthe box B. This guard is furnished at or near its middle with aholding-notch 7.; to receive the dump-lever and retain it in position tolock the dumpbars H in their upright or middle position, so as toprevent the accidental dumping of any of the sections.

The hinge edge of each section D or D is provided with a notch or recessd', to receive the circular portion of the lifting bar or cam f, whicheneircles the hinge-shaft F. It willv be observed that the lifting armsor cams ff foreach pair of sections are made integral with each otherand consist of a single loopshaped strap of metal. The lifting-arms forthe front section D are, however, made single instead of double, asthere is but one section to operate from the front hinge-shaft F.

The operation is as follows: To dump a load, the dumping-lever K isfirst moved in one direction, as shown in Fig. 2-say backward,asindicated in dotted lines-which operates to dump the alternate sectionsD D D by turning the dumping or leaf-supporting bars H H H backwarduntil the free edges of the levers or sections D D D will clear thecurved face 7L of the supporting-bars H. The dumping-lever K is thenmoved in the opposite direction and the sections or leaves D D dumped ina similar manner by the reverse movement of the supporting-bars H. Toelevate the sections,the operating-lever G is then first moved backward,thus rocking the shafts F and causing the lifting arms or cams f securedthereto to impinge against and raise the sections DD into the positionshown by dotted lines in Fig. 3, and then the dump-bar K is movedbackward to its farthest position, thus swinging the oscillating bars Ilunder the now raised sections D D', so as to support the same. Theoperator then in like mannerelevates the remaining or alternate sectionsD D D by throwing the operating-lever G forward, and then he moves thedump-lever K forward to its middle position, where it is held by thelocking-notch 7c, so that the free or meeting edges of the contiguoussections will restupon the curved face or web 7L of the dumping orsupporting bars H.
